A specific shade of red nail polish requires 7 parts red to 2 parts yellow. A mixture contains 35 quarts or red and 8 quarts of yellow. How can you fix the mixture to make the correct shade of red?
Answer: add 2 more yellow
Step-by-step explanation:
use the ratio 7 to 2 to solve for 35 to x
[tex]\frac{7}{2} =\frac{35}{x} \\70=7x\\x=10[/tex]
for 35 quarts of red, you will need 10 quarts of yellow to keep the ration proportional. Since it has 8 parts yellow, you need to add 2 more yellow

Answer:
2. 200.52 4. 212.67 5. 148.48
Step-by-step explanation:
for (2) you find the area of each shape first the square
12*12=144
then you find the area of the semicircle
the formula is A= (3.14)r^2/2
the (r) is 6 because that is half of the whole side of the semicircle
so... (3.14) 6^2/2
6*6= 36
(3.14)36/2
113.04/2
56.52
then add the 144 from the square to it
56.52+144
200.52
question (4)
-85.5 (area of the triangle)
-127.17 (area of the semicircle)
212.67
question (5)
-48( area of triangle)
-100.48 (area of semicircle)
148.48

Valeria already has $65 dollars in her savings account. If she puts $5 per week in her account, write and solve an inequality to find out how many weeks she must save to have at least $200 in her account.
Answer:
65 + 5x ≥200
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.
Mathematically speaking:
65 + 5x ≥200
If we solve it for x:
5x ≥200-65
5x ≥135
x ≥ 135/5
x ≥ 27 weeks
Feel free to ask for more if needed or if you did not understand something.

I'm trying to solve for X and X+Y. Please help me!
Answer:
From 12 o'clock position clockwise:
-12
-1
11
12
Step-by-step explanation:
y = -1 (given).
x + y = 11
Plug in -1 for y in the equation (given):
x + (-1) = 11
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:
x - 1 (+1) = 11 (+1)
x = 11 + 1
x = 12
x + y = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables:
12 + (-1) = 12 - 1 = 11
xy = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:
12 * -1 = -12

How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense
Answer:
They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.
In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.

Christy bought 9 tickets to the school play for her family. She paid for the tickets with $80.00 and received $18.35 in change. What was the price per ticket?
Answer:
6 dollars and 85 cents is the answer
Step-by-step explanation:
Hope this helps!
If you want to know how i did it, just let me know! :)
Answer:
$6.85
Step-by-step explanation:
Subtract the amount she gave by the change she got so it should look like this:
$80.00 - $18.35 = 61.65
Then you divide 61.65 by the amount of tickets
61.65 / 9 = 6.85

Which of the following has a slope of 3 and y-intercept of 4. Select all that apply
y=4x+3y is equal to 4 x plus 3
y = 3x + 4
y = 3x + 4
y = -3x - 4
y = -3x - 4
Answer:
[tex]y = 3x + 4[/tex]
y=mx+c, m represents the slope while c the y-intercept. (never forget that)

Desiree has $36 in her bank account. She spends $14.50 on dinner and tickets to a basketball game.
Which equation is set up to determine how much money Desiree has left in her bank account correctly, and how much money does she have left?
The equation x + 14.50 = 36 is used to determine how much money Desiree has left, and she has $21.50 left.
The equation x + 14.50 = 36 is used to determine how much money Desiree has left, and she has $21.50 left.The equation 14.50 + 36 = x is used to determine how much money Desiree has left, and she has $50.50 left.
The equation 14.50x = 36 is used to determine how much money Desiree has left, and she has $21.50 left.The equation 36x = 14.50 is used to determine how much money Desiree has left, and she has $50.50 left.
Answer:
B
X is how much is left, so adding the money spent to that should equal 36.

You are designing an icon for a mobil app. Use the provided ruler to answer the following questions.
a. Find the perimeter and area of the icon in the scale drawing. Round your measurements for the length and the width to the nearest half centimeter to calculate your answers.
The perimeter in the scale drawing is ____
centimeters.
The area in the scale drawing is ____
square centimeters.
b. Find the actual perimeter and area of the icon.
The actual perimeter is ____
millimeters.
The actual area is ____
square millimeters.
Please help me fill in the blanks also it shows 1cm:2.5mm, and the length is 3.5 and the width is 3.
Answer:
a. Scale Perimeter : 2.5 centimeters
Actual Perimeter : 13 centimeters
Actual Area : 10.5 square centimeters
b. Actual Perimeter : 130 mm
Actual Area : 1,050 mm
Step-by-step explanation:
a. 2.5 mm = 0.25 cm
2 (1 + 0.25) = 2.5
2 (3.5 + 3) = 13
3.5 x 3 = 10.5
b. 3.5 cm = 35 mm 3 cm = 30 mm
2 (35 + 30) = 130
35 x 30 = 1050

2. 0.1 ÷ 2 = 0.05
3. 0.05 + 23.7 = 23.75
this works because to find the middle of two numbers (in this explanation 10 and 20), you have to subtract the larger one from the smaller one (20 - 10 = 10) and take your sum and divide it by two (10 ÷ 2 = 5) and then add it back to the smaller number (5 + 10 = 15 = 1/2 the midpoint of 10 and 20)
